Apple revealed its intent to enter the healthcare market by adding two new components to iOS: Health, a separate companion app, and HealthKit, a hub for third-party apps related to health and well-being. Health is Apple's own application meant to help iPhone and iPad owners keep track of their health and fitness statistics, such as calories burned, weight fluctuations, and sleep patterns. HealthKit is for developers - who need to be careful about staying on the right side of the law when it comes to the privacy of healthcare information.
There are a lot of opportunities for developers in the healthcare space, but accessing the data needed to drive those applications can be maddeningly frustrating. There are no shortage of electronic medical record (EMR) systems, but they all have their own proprietary interfaces.
